PETER FONTAIN, OF NEW YORK, N. Y.

IMPROVEMENT IN GAS REGULATORS AND PURIFIERS.

Specification forming part of Letters Patent No. 37,500, dated January27, 1863.

.To all whom, it may conce n.

Be it known that I, PETER FONTAIN, of New York, of New York county, inthe State of New York, have invented a new and use ful Improvement inGas Regulators and Purifiers and I do hereby declare that the followingis a full and exact description thereof, reference being had to theaccompanying drawings, making part of this application.

My present invention relates to an improvement in the apparatus forwhich Letters Patent of the United Sates were granted to me on the 28thday of June, 1859; and my present-invention consists in providing thechamber in which the filtering material is placed with an orifice ormouth furnished with a suitable stopper, through which said filteringand regulating medium may be extracted and inserted, substantially ashereinafter more fully explained.

To enable those skilled in the art to make and use my improvement, Iwill proceed to describe the same, referring by letters to theaccompanying drawings, forming part of this application, and in which-Figure 1 is a perspective view of a regulator and purifier similar tothe one on which Letters Patent were granted to me, as above recited,with the addition of my present improvement. Fig. 2 is a longitudinalsection through the center of the same.

In the several figures the same letters of reference indicate the sameparts of the apparatus.

A and B are two frustuminal chambers, which are screwed (or otherwisefastened) together at their bases in such a manner as to form a thirdchamber, (J.

a and b are two filtering-disks, which may be made of perforated metal,wire-gauze, or other suitable material, and which impede the flow of gasand check the progress of foreign matters. Between these disks a b isarranged in the chamber 0 a mass of cotton, felt, sponge, or other.suitable substance, (as shown in red lines at Fig. 2,) through which thegas is made to pass and by which any irregularities of velocity areovercome during the percolation of the gas through said body of cottonor other substance.

D is an orifice or mouth in the chamber 0, and provided with ascrew-stopper, c, the obect of which will be presently explained.

E is a dirt-receptacle attached to the chamber A in a manner and for apurpose fully described in my former patent. From the op posite ends ofthe two frustums A B project two extensions in the forms of short pipescf, to which are connected the ends of the pipe which brings the gas tothe regulator and that which conducts it from the regulator to theburners. The course or direction of flow of the gas is illustrated byred arrows.

The operation of the apparatus in filtering and regulating the gas isthe same as that explained in my former patent, is also the operation ofthe removable dirt-receptacle E, and need not be described here.

It will be understood that the two extended portions 0 f of theapparatus are coupled or soldered to the supply-pipe, so that theregulator cannot have its two sections A B detached without detachingthe whole appara tus, from which it follows that the contents of chamber0 must remain in after the regulator is set up, unless some method ofremoval is provided for other than a detachment of the two frustums A B.By making an orifice or mouth, D, in the side or periphery of chamber 0,as shown, and providing it with a screwstopper, 0, I accomplish a simplemeans for the removal and reinsertion of the filtering and regulatingsubstance contained in chamber 0. It will be seen that by simplyremoving the stopper 0 the cotton or other substance packed in thechamber 0 maybe readily picked or pulled out and replaced.

Experience has shown that it becomes often necessary to renew thefiltering and regulating medium, and it will be seen that the modeherein described of accomplishing this desideratum is simple andeffective.

Having described the nature of my said improvement on my patentedapparatus of June 28, 1862, what I now claim as new, and desire tosecure by Letters Patent, is

The opening or outlet D, (provided with a suitable stopper,) incombination with the chamber 0 and its contents, substantially as andfor the purpose set forth.
